Definitions

  • the invention relates generally to X-ray apparatus having a stand comprising a swing arm for supporting an X-ray tube and X-ray detector.
  • a typical X-ray system comprises a swing arm (C-arc or G-arc) 1 supported proximal a patient table 2 by an arm 3 .
  • a swing arm C-arc or G-arc
  • an X-ray tube 4 and an X-ray detector 5 housed within the swing arm 1 , the X-ray detector 5 being arranged and configured to receive X-rays 6 which have passed through a patient 7 and generate an electric signal representative of the intensity distribution thereof.
  • the X-ray tube 4 and detector 5 can be placed at any desired location and orientation relative to the patient 7 .
  • U.S. Pat. No. 4,775,994 describes a mobile X-ray examination unit including a C-arm carrying an X-ray tube and an X-ray detector, wherein the C-arm is hinged generally centrally so that the X-ray tube and detector are moveable relative to each other in a substantially vertical direction relative to the patient. This enables the jaw size of the C-arm to be varied according to the size of the patient.
  • the jaw size needs to be relatively very large, for example, 1050 mm and in order to achieve this jaw size in known devices, even in the arrangement described in U.S. Pat. No. 4,775,994 having a variable jaw size, the resultant X-ray stand is unacceptably large.
  • an X-ray stand comprising a generally arcuate arm having opposing ends, wherein an X-ray source is provided at or adjacent one of said ends of said arm for generating an X-ray beam and an X-ray detector is provided at or adjacent the other of said ends of said arm, wherein said arcuate arm defines a jaw size comprising a distance between the primary axis of said X-ray beam and a point on said arm, wherein said X-ray stand further comprises means at or adjacent at least one of said ends of said arm for enabling movement of said detector and X-ray source relative to each other in a substantially radial direction relative to said arm, so as to selectively adjust said jaw size.
  • the detector and/or X-ray tube can be moved in a substantially vertical direction relative to a respective end of the arm, the maximum achievable jaw size is significantly increased relative to the prior art, without a significant increase in the size of the stand.
  • the stand comprises an elongate mounting arm having a first end pivotally mounted at or adjacent a first end of said arcuate arm and an opposing second end to which said detector is coupled.
  • the detector is coupled to the second end of the mounting arm by means of a pivotal joint.
  • a sliding mechanism is beneficially provided for selectively moving said X-ray source in a substantially radial direction relative to the arcuate arm.
  • the X-ray source may be mounted in or on a carriage coupled to a sliding mechanism.
  • the X-ray source is beneficially mounted within a housing which is coupled to the arcuate arm, at or adjacent an end thereof, and is stationary relative thereto.
  • means may be provided for enabling the orientation of the X-ray source to be selectively adjusted relative to a patient positioned between the ends of said arcuate arm.
  • FIG. 1 is a schematic side view of an X-ray swing arm according to the prior art
  • FIG. 2 is a schematic perspective view of an X-ray swing arm according to the prior art
  • FIG. 3 is a schematic side view of an X-ray swing arm according to an exemplary embodiment of the present invention, in a number of different configurations;
  • FIG. 4 is a schematic side view of an X-ray swing arm according to an exemplary embodiment of the present invention, when in use, defining a first jaw size
  • FIG. 5 is a schematic side view of an X-ray swing arm according to an exemplary embodiment of the present invention, when in use, defining a second jaw size.
  • an X-ray stand according to an exemplary embodiment of the present invention comprises a generally arcuate swing arm (C-arc or G-arc) 10 supported by an arm 12 .
  • the radius of the arcuate swing arm 10 may be, say, 940 mm.
  • Mounted within the swing arm 10 there is provided an X-ray tube 15 in a housing 14 and an X-ray detector 16 , the X-ray detector 16 being arranged and configured to receive X-rays 18 which have passed through a patient (not shown) and generate an electric signal representative of the intensity distribution thereof.
  • the X-ray tube 15 and detector 16 can be placed at any desired location and orientation relative to the patient.
  • the detector 16 is mounted via a smaller arm 20 to the swing arm 10 , adjacent the upper end thereof.
  • the smaller arm 20 is hingedly mounted to the swing arm 10 so as to enable the smaller arm 20 to pivot relative to the upper end of the swing arm 10 , about a Z-axis.
  • the detector plate 16 is mounted to the free end of the smaller arm 20 by means of a joint 22 which enables the detector plate 16 to be pivoted relative to the smaller arm 20 , again about a Z-axis.
  • an operator can adjust the position of the detector plate 16 in a substantially radial direction relative to the swing arm 10 by pivoting the smaller arm 20 , and the operator can also adjust the orientation of the detector plate 16 relative to the free end of the smaller arm 20 , so as to permit a number of different configurations, as shown in FIG. 3 .
  • the X-ray tube 15 is mounted on a pivotal carriage 15 a within the housing 14 such that it can be selectively tilted from a substantially horizontal orientation to an orientation at an angle to the X-axis, such that the primary axis of the X-ray beam 18 can be selectively changed from A to B.
  • the carriage 15 a in or on which the X-ray tube 15 is provided is mounted within the housing 14 on a sliding mechanism 30 which permits rotational movement of the X-ray tube 15 within the housing 14 (as indicated in FIG. 3 ).
  • the detector plate 16 is pivoted downwardly relative to the upper end of the swing arm 10 toward the patient 24 lying on the patient table 26 and the X-ray tube 15 is pivoted upwardly within the housing, toward the patient, as shown.
  • a jaw size 28 of, say, 1030 mm can be achieved with a swing arm 10 of radius 940 mm.
  • the configuration of the detector 16 and X-ray tube 15 may be adjusted such that a jaw size of, say 1050 mm can be achieved with a swing arm of radius 940 mm.
